BUSCADOR RECOLECTA

Between 1988 and 2016, we investigated the effects of breeding density and body size on natal dispersal propensity in a pied flycatcher (Ficedula hypoleuca) population breeding in nest-boxes in two different habitats in central Spain (41°04'N, 3°27'W − 40°40'N, 4°80'W). Body size was measured as tarsus length. Breeding density was estimated as the annual number of nest-boxes occupied by pied flycatchers relative to the total area of each forest patch. Dispersal rates between habitats were also calculated by dividing the number of recruits that moved from their natal to the alternative habitat patch by the total number of recruits that returned to the study area each year. In addition, we calculated the annual rates of immigration to each habitat, expressed as the number of unbanded birds relative to the total number of birds in a given year., Peer reviewed

This data set includes 9 years (2009-2017) of data on the number of red-necked nightjars (Caprimulgus ruficollis) encountered along a 24-km road network crossing a protected area of the Doñana Natural Park (Spain) 37°7′N, 6°33′ W. Nightjar counts were carried out on a weekly basis from the time of arrival from spring migration (early April) until autumn departure to their wintering quarters (late October). These counts began 1–2 h after sunset from fixed starting points by driving a vehicle at a constant speed of 30 km/h until the full 24-km route was completed. Meteorological information from the two nearest meteorological stations, located 17 km and 6 km from the study site, is also included in this data set., Peer reviewed

This data set is subjected to a Creative Commons Attribution 4.0 International Licence., This data set includes measurements of porphyrin-based pink fluorescence on the under-side of the wings of red-necked nightjars (Caprimulgus ruficollis). Data on date of capture, sex, age, extent of white plumage patches, and physical condition of each individual are also included in the data set. Fieldwork was carried out between 17 May and 16 September 2016 in a protected area of the Doñana Natural Park (Spain). Nightjars were captured during the night (1-6 h after sunset) along a 24-km road transect using a butterfly net, measured for standard morphological traits and photographed under standardized conditions using both white and ultraviolet lighting. Measurements of pink fluorescence and extent of the white patches were subsequently extracted from digital photographs., Peer reviewed

This data set is subjected to a Creative Commons Attribution 4.0 International Licence., This data set includes measurements of morphology, microhabitat selection, and reproductive success of male and female sockeye salmon (Oncorhynchus nerka) breeding in 1995 and 1996 in Pick Creek (59° 33’ 00’’N, 159° 04’ 18’’W), a small (2nd order) creek flowing into Lake Nerka, in the Wood River Lakes system, Alaska. The analysis presented in this article is based on 255 females (86 in 1995 and 169 in 1996) and 202 males (63 in 1995 and 139 in 1996).

The dataset contains the information of the pairs breeding in the population during the study years: breeding year (year), identity of the nest box (IDnestbox), its coordinates (GPSLONG & GPSLAT) and number of plot (Plot; there are two plots in the study area) wherein the pair bred. The file also contains the identity of the male (IDmale), the identity of the female (IDfemale), the mating status of the female (Polygyny = scored as 1 for the combination between the polygynous male and the secondary female) and its breeding date (Layingdate = day of the first egg, scored as days after 1st May). . To be published in Behavioral Ecology, Why females pair with already mated males and the mechanisms behind variation in such polygynous events within and across populations and years remain open questions. Here, we used a 19-year dataset from a pied flycatcher (Ficedula hypoleuca) population to investigate, through local networks of breeding pairs, the socio-ecological factors related to the probability of being involved in a polygynous event in both sexes. Then, we examined how the breeding contexts experienced by individuals shaped the spatial and temporal separation between broods of polygamous males. The probability of polygyny decreased with the distance between nests. Indeed, secondary females were often close neighbors of primary females, although the distance between both nests increased slightly with increasing synchrony between them. The probability of polygyny was also related to the breeding time of individuals, since early breeding males were more likely to become polygynous with late breeding females. Throughout the season, there was substantial variation in the temporal separation between primary and secondary broods, and this separation was in turn related to the breeding asynchrony of the polygamous males (in the primary nest) relative to the neighbors. Polygynous males that bred late relative to their neighbors had a short time window to attract a second female and thus the breeding interval between their primary and secondary broods was reduced. Overall, the spatial proximity between polygynous males’ broods and, if the opportunity existed, their temporal staggering are compatible with a male strategy to maximize paternity and reduce the costs of caring for two broods, though the effect of female’s interest, either primary or secondary, cannot be fully ruled out. We highlight that a comprehensive assessment of the breeding contexts faced by individuals is essential to understand individual mating decisions and reconcile the discrepancies raised by previous work on social polygyny., Peer reviewed
